<h2>Examples
</h2>
<p>The examples below use the XML file
<a target="_blank" href="books.xml">books.xml</a>. <br />
A function, <a href="dom_loadxmldoc.asp">loadXMLDoc()</a>, in an external JavaScript is used to load the XML file.</p>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createelement1">Create an
element node</a><br />
This example uses createElement() to create a new element node, and appendChild() to
add it to a node.</p>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createattribute">Create an attribute
node using createAttribute </a><br />
This example uses createAttribute() to create a new attribute node, and
setAttributeNode() to insert it to an element.</p>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createattribute3">Create an attribute
node using setAttribute </a><br />
This example uses setAttribute() to create a new attribute for an element.</p>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createelement1">Create a
text node</a><br />
This example uses createTextNode() to create a new text node, and appendChild() to
add it to an element.</p>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createcdatasection1">Create a CDATA section node</a><br />
This example uses createCDATAsection() to create a CDATA section node, and
appendChild() to add it to an element.</p>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createcomment1">Create a
comment node</a><br />
This example uses createComment() to create a comment node, and appendChild() to
add it to an element.</p>
<hr />
<h2>Create a New Element Node</h2>
<p>The createElement() method creates a new element node:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table18">
<tr><td>
<pre>xmlDoc=loadXMLDoc("books.xml");
newel=xmlDoc.createElement("edition");
x=xmlDoc.getElementsByTagName("book")[0];
x.appendChild(newel);</pre>
</td></tr>
</table>
<p>Example explained:</p>
<ol>
<li>Load "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
<li>Create a new element node <edition></li>
<li>Append the element node to the first <book> element</li>
</ol>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createelement2">Try
it yourself</a></p>
<p>Loop through and add an element to all <book> elements:
<a target="_blank" href="tryit.asp@filename=try_dom_createelement">Try
it yourself</a><br />
</p>
<hr />
<h2>Create a New Attribute Node</h2>
<p>The createAttribute() is used to create a new attribute node:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table31">
<tr><td>
<pre>xmlDoc=loadXMLDoc("books.xml");</pre>
<pre>newatt=xmlDoc.createAttribute("edition");
newatt.nodeValue="first";</pre>
<pre>x=xmlDoc.getElementsByTagName("title");
x[0].setAttributeNode(newatt); </pre>
</td></tr>
</table>
<p>Example explained:</p>
<ol>
<li>Load "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
<li>Create a new attribute node "edition"</li>
<li>Set the value of the attribute node to "first"</li>
<li>Add the new attribute node to the first <title> element</li>
</ol>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createattribute">Try
it yourself</a></p>
<p>Loop through all <title> elements and add a new attribute node:
<a target="_blank" href="tryit.asp@filename=try_dom_createattribute2">Try
it yourself</a></p>
<p><b>Note:</b> If the attribute already exists, it is replaced by the new one.</p>
<hr />
<h2>Create an Attribute Using setAttribute()</h2>
<p>Since the setAttribute() method creates a new attribute if the attribute does
not exist, it can be used to create a new attribute.</p>
<table class="ex" id="table32" border="1" cellspacing="0" width="100%">
<tr>
<td>
<pre>xmlDoc=loadXMLDoc("books.xml");</pre>
<pre>x=xmlDoc.getElementsByTagName('book');
x[0].setAttribute("edition","first");</pre>
</td>
</tr>
</table>
<p>Example explained:</p>
<ol>
<li>Load "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
<li>Set (create) the attribute "edition" with the value "first"
for the first <book> element</li>
</ol>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createattribute3">Try
it yourself</a></p>
<p>Loop through all <title> elements and add a new attribute:
<a target="_blank" href="tryit.asp@filename=try_dom_createattribute4">Try
it yourself</a></p>
<hr />
<h2>Create a Text Node</h2>
<p>The createTextNode() method creates a new text node:</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table25">
<tr><td>
<pre>xmlDoc=loadXMLDoc("books.xml");</pre>
<pre>newel=xmlDoc.createElement("edition");
newtext=xmlDoc.createTextNode("first");
newel.appendChild(newtext);</pre>
<pre>x=xmlDoc.getElementsByTagName("book")[0];
x.appendChild(newel);</pre>
</td></tr>
</table>
<p>Example explained:</p>
<ol>
<li>Load "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
<li>Create a new element node <edition></li>
<li>Create a new text node with the text "first"</li>
<li>Append the new text node to the element node</li>
<li>Append the new element node to the first <book> element</li>
</ol>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createelement1">Try
it yourself</a></p>
<p>Add an element node, with a text node, to all <book> elements:
<a target="_blank" href="tryit.asp@filename=try_dom_createelement">Try
it yourself</a></p><hr />
<h2>Create a CDATA Section Node</h2>
<p>The createCDATASection() method creates a new CDATA section node.</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table29">
<tr><td>
<pre>xmlDoc=loadXMLDoc("books.xml");</pre>
<pre>newCDATA=xmlDoc.createCDATASection("Special Offer & Book Sale");</pre>
<pre>x=xmlDoc.getElementsByTagName("book")[0];
x.appendChild(newCDATA);</pre>
</td></tr>
</table>
<p>Example explained:</p>
<ol>
<li>Load "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
<li>Create a new CDATA section node</li>
<li>Append the new CDATA node to the first <book> element</li>
</ol>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createcdatasection1">Try
it yourself</a></p>
<p>Loop through, and add a CDATA section, to all <book> elements:
<a target="_blank" href="tryit.asp@filename=try_dom_createcdatasection">Try
it yourself</a><br />
</p>
<hr />
<h2>Create a Comment Node</h2>
<p>The createComment() method creates a new comment node.</p>
<table width="100%" border="1" class="ex" cellspacing="0" id="table30">
<tr><td>
<pre>xmlDoc=loadXMLDoc("books.xml");</pre>
<pre>newComment=xmlDoc.createComment("Revised March 2008");</pre>
<pre>x=xmlDoc.getElementsByTagName("book")[0];
x.appendChild(newComment);</pre>
</td></tr>
</table>
<p>Example explained:</p>
<ol>
<li>Load "<a target="_blank" href="books.xml">books.xml</a>"
into xmlDoc using <a href="dom_loadxmldoc.asp">loadXMLDoc()</a> </li>
<li>Create a new comment node</li>
<li>Append the new comment node to the first <book> element</li>
</ol>
<p><a target="_blank" href="tryit.asp@filename=try_dom_createcomment1">Try
it yourself</a></p>
<p>Loop through, and add a comment node, to all <book> elements:
<a target="_blank" href="tryit.asp@filename=try_dom_createcomment">Try
it yourself</a><br />
